1.首先创建登录帐号和密码文件 

htpasswd 默认不带 需要安装web套件

例如:

帐号：admin 密码：123456

htpasswd -Bbn admin 123456 > /volume1/dockerapp/registry/auth/passwd

2.创建容器项目 

compose.yaml文件 

version: '3.8'

services:
  registry-ui:
    image: joxit/docker-registry-ui:main
    restart: always
    ports:
      - 6006:80
    environment:
      - SINGLE_REGISTRY=true
      - REGISTRY_TITLE=Docker Registry UI
      - DELETE_IMAGES=true
      - SHOW_CONTENT_DIGEST=true
      - NGINX_PROXY_PASS_URL=http://registry-server:5000
      - SHOW_CATALOG_NB_TAGS=true
      - CATALOG_MIN_BRANCHES=1
      - CATALOG_MAX_BRANCHES=1
      - TAGLIST_PAGE_SIZE=100
      - REGISTRY_SECURED=false
      - CATALOG_ELEMENTS_LIMIT=1000
    container_name: registry-ui

  registry-server:
    image: registry:2.8.2
    restart: always
    environment:
      REGISTRY_HTTP_HEADERS_Access-Control-Allow-Origin: '[http://192.168.2.3:5000]'
      REGISTRY_HTTP_HEADERS_Access-Control-Allow-Methods: '[HEAD,GET,OPTIONS,DELETE]'
      REGISTRY_HTTP_HEADERS_Access-Control-Allow-Credentials: '[true]'
      REGISTRY_HTTP_HEADERS_Access-Control-Allow-Headers: '[Authorization,Accept,Cache-Control]'
      REGISTRY_HTTP_HEADERS_Access-Control-Expose-Headers: '[Docker-Content-Digest]'
      REGISTRY_STORAGE_DELETE_ENABLED: 'true'
      REGISTRY_AUTH: 'htpasswd'
      REGISTRY_AUTH_HTPASSWD_REALM: 'Registry Realm'
      REGISTRY_AUTH_HTPASSWD_PATH: '/etc/registry/auth/passwd'
      DELETE_IMAGES: 'true'
    volumes:
      - /volume1/dockerapp/registry/data:/var/lib/registry
      - /volume1/dockerapp/registry/auth:/etc/registry/auth
    container_name: registry-server

这里5000端口，不会映射到外边，必须是5000，否则webui会报错。

只需要修改以下几处地方为自己的即可

3.docker客户机上传

 win平台docker为例

docker中增加

"insecure-registries": ["192.168.2.3:6006"]

如图

上传操作

#登录私服
docker login 192.168.2.3:6006
输入帐号admin 密码123456 登录成功

#拉取官方镜像
docker pull gitea/gitea:latest
#修改标签
docker tag gitea/gitea:latest 192.168.2.3:6006/gitea/gitea:latest
#上传镜像到私服
docker push 192.168.2.3:6006/gitea/gitea:latest

查看上传镜像
